A new triterpenic acid from roots of Rosa multiflora var. cathayensis / 中草药

ABSTRACT

Objective To study the chemical from the roots of Rosa multiflora var. cathayensis. Methods The silica gel column chromatography was used to separate the chemical constituents from the roots of Rosa multiflora var. cathayensis. HPLC was used to analyze its purity, chemical and spectroscopy methods were used to determine their structures. Results Nine constituents were isolated and identified as multifloside A (1), arjunic acid (2), 1β-hydroxyeuscaphic acid (3), arjunetin (4), kaji-ichigoside F1 (5), euscaphic acid (6), tormentic acid (7), myrianthic acid (8), and rosamultin (9). Conclusion Compound 1 is a new compound named multifloside A; All compounds are obtained from the genus Rosa for the first time.
